For example, if the time slider is at frame 35, and
the Frame Rate is set to 30 fps, the time slider
would display the following numbers for the
different Time Display sett ings:
•Frames:35
•SMPTE:0:1:5
FRAME: TICKS: 35:0
MM:SS: TICKS: 0:1:800
SMPTE is the
Society of Motion Picture Technical

and television production.
Playback group
Real Time
Real Time (page 3–1095)
causes
viewport playback to skip frames to keep up with
thecurrentFrameRatesetting.Achoiceoffive
playbackspeedsisavailable:1xisnormalspeed,
1/2x is half speed, and so on. The speed settings
affect only the playback in the viewport s.
These speed settings c an also be used with the
Motion Capture uti lity (page 2–632)
.
When Real Time is off, viewport playback occurs
as r apidly as possible and displays all frames.
Active Viewpor t Onl y—Causes playback to occur
only in the active viewport. When off, all
viewports display animation.
Loop—Controls w hether t he animation playback
occurs o nly once, or repeatedly. When on,
playback repeats until you stop it by clicking
an animation control button or the time slider
channel. When off, the animation plays once and
then stops. Clicking Play rewinds to the first frame
and plays again.
Direction—Set the animation to play for ward,
reverse, or ping-pong (forward and then reverse,
repeating). This affects only the playback in
the interact ive renderer. It does not apply when
rendering to any image output file. These options
are available only when Real Time is off.
These settings can be recalled by saving to a
maxstart.max
file.
Animation group
Star t T ime/End T ime—Sets the
active time segment
(page 3–998)
displayed in t he time slider. Choose
any time segment before or af ter frame 0. For
example, you can set an active time seg ment f rom
-50 to 250.
Lengt h—Displays the number of frames in the
active time segment. If you make this greater than
thetotalframesintheactivesegment,theEnd
Time field increases accordingly.
Fr am e Cou n t The number of frames that w ill
render. Always the length plus one.
Curr ent T ime—Specifies the current frame for the
time slider. As you adjust this, the time slider
moves accordingly and the viewport updates.
Re-scale TimeStretches or shrinks the animation
for the active time segment to fit into the new time
segment you specify. Relocates the position of all
keys (page 3–1054)
in all tracks. As a result, the
animation plays over a greater or lesser number of
frames, making it faster or slower.
